Naturally, attention has turned to a potential fight with retired pound-for-pound king Floyd Mayweather given the pair’s traded barbs and frequent discussion of a crossover meeting.

However Las Vegas resident Mayweather exclusively fights in Nevada and any potential comeback he may make is all but certainly going to take place in Sin City.

McGregor was recently stripped of his UFC featherweight title, which he claimed by knocking out all-time great Jose Aldo in 13 seconds, prompting criticism from the Irishman’s team.

While an immediate fight with Mayweather looks unlikely, McGregor could be aiming to carve out some sort of career in boxing, having started out as a novice amateur at the Krumlin Boxing Club in Dublin before he took up mixed martial arts.

However, it is relatively easy to get a licence in California and McGregor’s latest move could all be a ploy to keep him in the news and keep the UFC’s new owners on their toes.
